A vertically sliding roll-up door has a portal structure including vertical uprights provided with guide rails for guiding the sliding of blocks fixed along the lateral edges of the curtain, to allow the curtain to move vertically with respect to the portal structure. The curtain includes air-sealing gaskets which extend substantially over the entire length of the longitudinal edges of the curtain at the blocks, in order to block the passage of air between the guide rails and the blocks.

A closure may include a door configured to seal an opening. The door may include a section with an internal cavity. The closure may also include a core within a first portion of the internal cavity of the section. The core may be configured to expand from a relaxed state to an expanded state and provide a seal between the door and an edge of the opening when the core is in the expanded state.

A blockout blind system includes side tracks fitted with brushes in conjunction with a pelmet fitted with flaps ensure no light can pass around the blind. The flaps and brushes have offset apertures either side of the blind to allow for airflow thus preventing the blind being sucked out or pushed in by open or leaking windows and air conditioning systems. The system also conceals the chain for operating the blind thus eliminating strangulation hazards for children and animals. The design allows the system to be fitted to existing roller blinds.

To provide a shade guide structure which can be used for an application in which the guide rails are curved, in which the sliding resistance is low, and which can reduce abrasion, a shade guide structure includes: a shade sheet wound around a winding shaft so that the shade sheet can be wound up and drawn out; guide belts provided along either side edge of the shade sheet and each joined to the shade sheet via a fixation part provided substantially at a center in a width direction; and left and right guide rails which guide the guide belts in a longitudinal direction when the shade sheet is wound up or drawn out, wherein each guide rail includes: a guide wall having a lock surface which is inclined relative to the shade sheet in a transverse cross section and locks the guide belts; a slot which is formed in the guide wall and through which the shade sheet passes; and a guide part which contacts the shade sheet such that the shade sheet extends from the fixation part substantially at a right angle to the guide belt.

A quick-action roll-up door (1) for a cold storage room has a flexible door panel (5), which is windable onto a horizontal shaft (4) in a vertical running direction for purposes of closing a door opening (2) bounded by a door frame (3). A winding drive (6) opens and closes the door, together with a pressure application frame (8), subjecting the door panel in a closing position to force, transverse to a planar face of the door panel, in the direction of the door frame. Furthermore, device features are provided, which apply force to the pressure application frame in the direction of the door frame when the roll-up door is closed, and relieve it when it is opened. The device features have a traction drive (14), which is functionally connected to the winding drive for the door panel, and which controls the movement of the pressure application frame.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly. The sash includes at least one magnet. The sash is slideably engaged with the frame. The at least one screen assembly includes a roller assembly, a control bar, and screen material attached to the roller assembly and the control bar. The roller assembly is substantially hidden from view. The control bar includes a ferromagnetic material. The screen assembly is configured to apply tension to the screen material to wind the screen material around the roller assembly and to permit the screen material to unwind from the roller assembly under a tension applied to move the control bar away from the roller assembly. The control bar automatically engages the at least one magnet of the sash when the sash is in the closed configuration to attach the control bar to the sash.

A high speed roll door is movable between an open and a closed position at an opening of a building. The door includes a flexible curtain and a pair of side columns. Each side column provides an inner track to guide the curtain in vertical movement and restrain the curtain from lateral movement during deployment and retraction. The curtain further includes multiple cross bars supporting the flexible curtain from one of the pair of side columns to the other. Each of the cross bars further includes a first longitudinal bar sandwiching part of the curtain; and a second longitudinal bar pivotally connected to the first longitudinal bar. The hinge has an axis of rotation parallel to the first and the second longitudinal bars. At least a wheel is rotatably affixed to each end of the second longitudinal bar to engage the inner track of each of the side columns.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly mounted in at least one of: the top portion and the bottom portion. The frame includes a top portion, a bottom portion, and two jambs forming first slots extending lengthwise along at least a portion of the jamb. The first slots each include a screen edge retention feature. The screen assembly includes a roller assembly substantially hidden from view, a screen material attached to the roller assembly, and a plurality of raised features. Edges of the screen material extend into the first slots. The raised features are attached to each of the edges of the screen material. The raised features are configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.

A perimeter light blockout system for minimizing light leakage between light gaps such as, for example, between the sides of a covering (e.g., shade) of an architectural-structure covering and the interior side surfaces of a window frame, or between the covering and the outer surface of an interior wall is disclosed. The perimeter light blockout system including a light blocking device and a mounting element for coupling the light blocking device to the interior side surface of the window frame, or the outer surface of the interior wall. The light blocking device may include rear and front channel members. The mounting element may be a mounting extrusion. Alternatively, the mounting element may be a spring clip. In use, the light blocking device may be adapted and configured so as not to contact the covering as the covering moves between extended and retracted positions. The mounting element may include a degree of adjustment so that the light blocking device may be aligned with an out-of-skew window frame.

A door, in particular vertical-lift door, for closing an opening in a wall, in particular in a wall which separates two different temperature zones from one another, having a movable, flexible door leaf which comprises multiple separate, flexible door leaf layers which are guided such that they are spaced apart from one another in the closed state of the door, and having at least one winding shaft onto which the door leaf can be wound up in order to open the door, in which two adjacent door leaf layers are connected to one another by at least one spacer which ensures a spacing, defined by the spacer, of the two door leaf layers at least in the region of the spacer in the closed state of the door.
